Complete the CarMuseum class below so that it implements the given Measurable interface. Your tasks are as follows:

Modify the CarMuseum class to implement the Measurable interface.
In the constructor of CarMuseum, process the input string, and add unique cars to the arraylist (do not add duplicates).
Implement the method in Measurable within CarMuseum to return the count of cars in the museum.

For example, if the input string is "1949 Ford,1943 Studebaker,1950 Chevrolet,1948 Pontiac,1949 Ford,1944 Pontiac,1949 Studebaker", then the getMeasure method of the CarMuseum class should return 6.0.

Complete the following file:

CarMuseum.java

/** Allows input of unique cars into the museum. */ // TODO: modify this class to implement the Measurable interface import java.util.*; public class CarMuseum { private ArrayList<String> cars; public CarMuseum(String input) { cars = new ArrayList<String>(); // TODO: complete this method to add // cars from the input string. Only // allow unique cars to be added (no // duplicates). } /** Returns the count of cars @return the count of cars in the museum */ // TODO: Implement the getMeasure method from the interface }

Use the following files:

CarMuseumTester.java

/**
   Tests the CarMuseum class.
*/
public class CarMuseumTester
{
   public static void main(String[] args)
   {
      CarMuseum museum = new CarMuseum("1949 Ford,1943 Studebaker," +
         "1950 Chevrolet,1948 Pontiac,1949 Ford,1944 Pontiac,1949 Studebaker");
      System.out.println("Number of cars in garage: " + museum.getMeasure());
      System.out.println("Expected: 6.0");
   }       
}

Measurable.java

public interface Measurable
{
   double getMeasure();
}
